MACHlNE FOR WEAVING WIRE.

SPECIFICATION forming part of Letters Patent No. 562,641, dated June 23,1896.

Application filed November 6, 1895.

To all whom it may concern.-

Be it known that I, WILLIAM XV. MCOAL- LIP, a citizen of the UnitedStates, residing at Columbus, in the county of Franklin and State ofOhio, have invented certain new and useful Improvements in Machines for"Weaving ire; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

Vvhile my invention relates generally to machines for weaving wire, itis my particular object to produce a simple and inexpensive machine forweaving diamond or the so- -called diamond-mesh wire fabric, that is,

fabric in which the wires lie diagonally to the direction of the lengthof the fabric, whether the mesh be of square or rhombus form.

The invention consists generically of a machine comprising a single pairof devices, one of which has a series of elevators and the other aseries of depressors, the elevators alternating with the depressors, andmeans for moving the fabric so that the strands will be carried forwardand laterally along the line of the elevators and depressors to move'thestrands alternately from an elevator to a depressor to form the shed inthe process of the weaving.

The invention further comprises details incident to the features alreadymentioned, all of which will be hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a plan view of theweaving-machine, parts being omitted for the sake of clearness. Fig. 2is a view in side elevation of the upper part of the machine. Fig. 3 isa sectional and elevational view, on a larger scale, intended Fig. 4 isa fragmentary side view of the beatershaft. Fig. 5 is a sectional view,on a small scale, illustrating the rollers for feeding or rolling thewoven fabric.

Like characters of reference in the different views designatecorresponding parts.

1 designates the table. In suit-able housings on two adjoining edges ofthis are mounted the top shafts 2 2 and bottom shafts 2 2, which supportbars 3 and 4, respectively, hav ing wire-elevating fingers l anddepressing- Serial No. 668,073. 0 model-l fingers 3. The bars 3 and 4:are preferably removably attached to the shafts, and for this purposethe shafts may be made with a socket or groove 5, into which the barsare placed and held by set-screws 6 and the fingers are so cast, formed,or placed as to pass freely between each other when the shafts arerotated. Further, the ends of the fingers have notches or recesses 3 and4 as shown in Fig. 2, so as surely to engage and receive the wires whenthey are turned up or down against the same and retain them in parallelposition.

In order that all four shafts or finger-bars may be rotated with therotation of one of them, the upper two may be geared together by gears,as shown at 7 and these two to the two lower ones by gears, as shown at8. Supportedin suitable brackets, so as to extend diagonally across thetable, and in a line subtending the angle of the two pairs of shafts, Iarrange a roller 9, preferably having a roughened surface, which isgeared, as shown at 10, to be rotated by the upper gears 8. Anidle-roller 11, (see Fig. 5,) similar to the roller 9, is placed toextend along an opening 20 in the table under and parallel to the roller9, and is held in contact therewith by suitable springs 5' in anywell-known manner.

To secure the strands in place during the shedding operation, the edgesof the table parallel to the finger-bars are furnished with strips 12",rcmovably secured thereto by setscrews, the said strips having beads 12with rounded surfaces projecting upwardly and located at intervals, soas to form spaces or grooves 12 between them equal to the distancebetween the parallel wires of the fabric. lhe spaces or grooves betweenthe beads receive and permit the depression of alternate wires, as shownin Fig. 3, and the walls of the grooves serve to retain the wires inproper position during the weaving process. As the corners of the beadsare rounded they do not interfere with the lateral movement of the wiresalong the line of the fingers under the action of the rollers. lhesebeaded strips, as well as the finger-bars 3 and i, are made removable,so that others may be substituted in their places to adapt the machinefor the weaving of fabric of different size of mesh.

On opposite corners of the table are adjustably-placed guides 13, (seeFig. 1,) by means of which the operator can determine the .distance towhich the cross or weft wire is to be inserted in the shed.

Journaled on the table, a little below and parallel to the edge orbeaded strip thereof, is a shaft 14, (see Fig. 3,) which is made with alongitudinal groove to receive beater-arms 15, which are adj ustablyfixed in suitable number and at proper distance apart. Upon the shaft 14is a segmental gear 16 to be engaged by a similar segmental gear 16,fixed on the shaft 2. The shaft 14 is provided with a spring 17, whichtends to hold the shaft so that the beater-arms normally stand inhorizontal position, and the segmental gear 16' is arranged on its shaftso that it will not, in the course of its rotation, engage the gear 16until after the cross or weft wire has been passed into the shed. Thecontinued rotation of the shaft 2 throws the beater-arms up into avertical position, (see dotted line, Fig. 3,) thus pushing the weftwireinto its proper place in the fabric. There are, of course, two of theshafts 14, one for each operating edge of the table, and they may begeared together in substantially the same way as are the upper shafts 22, the operation of one of them effooting the simultaneous operation ofthe other.

The machine may be driven by hand or other motive power. When it isdesired to operate it by hand, a crank cmay be provided, as shown at theleft-hand side of Figs. 1 and 2, and when to be driven by steam orelectricity a band-pulleyb may be provided, as indicated at theright-hand side of said figures. \Vhen the band-pulley is employed, aclutch or other power shifting device may be serviceable to discontinuethe rotation of the shaft during the insertion of the weft or crosswire.

Either crimped or plain wire may be woven with my machine, but crimpedwire is now most frequently used and my construction, as shown, is moresatisfactorily adapted to it.

The gear-wheels put upon the roller 9 are of such size or proportionwith respect to gears 8 as to move or advance the fabric a distanceequal to one mesh during one revolution of the finger-shafts 2 and 2-,so that the fingers successively elevate and depress the wires to formthe shed and permit the interweaving of the weft or cross Wires.

In operation, the strands are out to the proper length, that is, thediagonal width of i the. fabric in the direction in which the strandslie. A sufficient number are placed in the machine to start the weavin'g, and the work is then continued by introducing, by hand, the wires atthe lower left-hand corner of the machine, the guides 13 serving tosecure the proper alinement of the ends of the wires when placing themin the machine.

It will be understood, of course, that I do not confine myself to thevarious details of construction shown, as they may be modified withoutdeparting from the scope of my invention. i

It is also obvious that other mechanism equally well adapted for movingthe fabric may be substituted for the roller 9 and its mate.
